The combustion behavior of the aluminum particles near the burning surface of the aluminized composite propellant was studied. The combustion of the strand in the strand burner and the computational fluid dynamics (CFD) around the burning aluminum particle were performed. The temperature histories from combustion experiments and the temperature distributions from CFD were obtained. The temperature fluctuations of the burning aluminum particles in the temperature histories were observed. The aluminum particles ignite and burn near the burning surface. When the aluminum particles ignite much nearer the burning surface, the temperature gradient is increased in the reaction zone. The burning aluminum particle made a streamline shaped high temperature area around it. Therefore the burning aluminum particle could increase the temperature of the combustion gas widely, the temperature gradient near the burning surface was increased and the burning rate was increased.
